Question about Truvada

I just recently started taking Truvada. I am well aware that it is not 100% fullproof against HIV although I hear some men are acting like it is. My question is does anyone know anyone personally that became HIV+ while taking Truvada? Because I've been to a couple of websites and the statistics vary, so I would kind of like to hear some personal stories. Obviously I understand it's a very sensitive and personal subject so I really appreciate any answers and understand if this gets none. And don't worry I'm not about to go barebacking all over scruff. Thanks!
